Fix QEMU tunnelled migration FD handling
Fix QEMU tunnelled migration FD handling

The two ends of the pipe used for feeding QEMU tunnelled
migration data were interchanged, so QEMU got given the
"write" end instead of the "read" end.

The qemuMigrationPrepareTunnel method was also immediately
closing the "write" end of the pipe, so the stream failed
to actually write anything.

* src/qemu/qemu_migration.c: Swap tunnelled migration
  pipe FDs & don't close pipe given to stream
